HOW TO SKIM READ THIS SHOULD REALLY BE UPDATED TO TAKE INTO ACCOUNT INF LIT SKILLS
Is the book or site you are looking at relevant?
What do you really want to know?
What does the article cover?

SKIM READ to find out an overview of the book article or chapter.
  • Read the 1st, 2nd and last paragraph
  • Read all sub headings and picture captions

This will give you a good general idea of what is covered, as well as an idea of the reading level -ie: to hard? easy to read?
